Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Fracture and Deformation in Bulk Metallic Glasses and Composites
(2018-01-11)Plastic flow in bulk metallic glasses (BMGs) localizes into narrow bands, which, in the absence of a microstructure that could obstruct them, propagate unhindered under tensile loading. In constrained deformation conditions ... -
Fracture And Fatigue Behavior Of Concrete-Concrete Interfaces Using Acoustic Emission, Digital Image Correlation And Micro-Indentation Techniques
(2011-04-05)Currently, the maintenance and repair of civil engineering infrastructures (especially bridges and highways) have become increasingly important, as these structures age and deteriorate. Interface between two different mixes ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Fracture Behaviour including Size Effect of Cement Stabilised Rammed Earth
(2018-01-30)Rammed earth is a monolithic construction formed by compacting processed soil in progressive layers. Rammed earth is used for the construction of load bearing walls, floors, sub base material in roadways, airport runways, ... -
Fracture Characteristics Of Self Consolidating Concrete
(2010-07-16)Self-consolidating concrete (SCC) has wide use for placement in congested reinforced concrete structures in recent years. SCC represents one of the most outstanding advances in concrete technology during the last two ... -
Fracture Energy And Process Zone In Plain Concrete Beams (An Experimental Study Including Acoustic Emission Technique)
(2013-05-20)Concrete, which was hitherto considered as a brittle material, has shown much better softening behavior after the post peak load than anticipated. This behavior of concrete did put the researchers in a quandary, whether ... -
Fracture Of Plain Concrete Beams Via Fractals
(2009-09-02)The quantitative description of rough fracture surfaces of concrete has been an important challenge for many years. Looking at the fracture surface of a concrete specimen, one realizes that the self-affine geometry of crack ... -
A Framework for Effectiveness-based Sustainability Assessment in Manufacturing – A Product Life Cycle Approach
In recent decades, various human health impacts and environmental concerns (e.g., microplastic pollution, chemical exposure, biodiversity loss) associated with manufacturing/product life cycles have surfaced, threatening ... -
A framework for optimizing immunotherapy for long-term control of HIV
HIV infects around 1 million people every year. Antiretroviral therapy (ART) is used to suppress viral replication and control disease progression but it cannot eradicate the virus. ART is therefore lifelong. Today, e ... -
A Framework to Measure the Socio-Economic Impact of Development Programs Using Malmquist Index
(2018-06-08)The main objective of this research is to evaluate the socio economic impact of the development programs like MGNREGA, JnNURM and development of Roads project, on the intended target area. The entire thesis can be divided ... -
Frequency Analysis of Floods - A Nanoparametric Approach
(2018-04-18)Floods cause widespread damage to property and life in different parts of the world. Hence there is a paramount need to develop effective methods for design flood estimation to alleviate risk associated with these extreme ... -
Frequency-Tuning and Dynamic Simulation of Electrostatically Actuated Beams
(2018-01-03)The resonance frequency of electrostatically actuated micromachined beams can be tuned substantially by applying a DC voltage bias, first by decreasing the frequency until the onset of pull-in and then by increasing it by ... -
From Particles to People: Vicsek-Inspired Behavioural Modelling Frameworks
In this thesis, we develop different modelling frameworks to capture the processes of opinion formation and disease spread. The common theme binding them is a nearest-neighbour-based interaction rule; while the closeness ... -
Fuel Drop Splashing on Heated Solid Surfaces
Droplet-wall interactions on heated surfaces are significantly encountered in applications such as fuel spray impingement in combustors and spray cooling. The present thesis is focused on the splashing of fuel drops on ... -
Fuel Filim Visualization And Measurement In The Inlet Manifold Of A Carbureted Spark-Ignition Engine
(2013-10-01)In order to meet future emission norms for small carbureted SI engines, such as those used on motorcycles in India, there is a need to study mixture preparation, specifically the two-phase flow exiting the carburetor and ... -
A Fundamental Investigation Of Discrete Liquid, Gas And Fines Flow In A Random Packed Bed Along With Applications
The discontinuous nature of liquid flow in a random packed bed is observed in many chemical engineering and metallurgical applications like blast furnace and heap leaching. So, to model the liquid flow in these systems, ... -
Fundamental Studies On Tribological Response Of Titanium And Copper
(2007-08-22)Friction and wear have been observed m mechanical systems when there is a relative motion between two solid bodies Friction mainly results in loss of energy and wear results in matenal loss The proper understanding of ...
